ABSTRACT: This work proposes the design of a complete, compact, hybrid atom chip system for producing ultracold atoms, allowing subsequent control and manipulation of ultracold atoms using both optical and magnetic fields. Its emphasis is on optical lattice potentials and also complex potentials imposed by spatially varying magnetic and optical fields. Atom chips that incorporate optical windows ...

ABSTRACT: Military and other software systems often face the need to accept untrusted software components into the system. The proposed research will enable secure integration of untrusted software components by (1) isolating these components using application-level (per-process) virtualization; (2) assisting the customer in constructing a security policy tailored to each untrusted component; (3) ...

ABSTRACT: This proposal details an ambitious effort to develop Virtualization-based secure application Containers and Controlled Communication System (VC3S). The VC3S provides secure application/module isolation, mediation of inter-application/module communication, as well as dynamic/intelligent exposure to the Internet. The proposed approach is three-pronged and enables the application of the pr ...

ABSTRACT: One of the Air Force main interests is to improve the antireflective (AR) optical properties of polycarbonate by exploring new coating materials or coating techniques to eliminate delamination and stress cracks due to the mismatch in the coefficient of thermal expansion between the coatings and the polymer substrates. SwRI and INTER Materials are in a unique position to assist the Air F ...

ABSTRACT: We propose to develop modeling and initial concept feasibility demonstration for MWIR lasers that span the 2.4-4 um wavelength span. The laser active region design is based on a novel quantum well design that is grown on InP substrates. The laser will leverage our team's recent advances and demonstrations in quantum well design be use Princeton Lightwave's laser fabrication pl ...

ABSTRACT: Harvesting electrical energy from thermal gradients can be a useful tool for numerous applications from large scale waste heat recovery to small scale self-powered sensors. Increasing the efficiency of traditional bulk thermoelectric generators (TEG) has been the subject of much development for 30-40 years yet efficiency improvements for commercially viable devices have been marginal. ...

ABSTRACT: Mycotoxins represent a class of potential chemical/biological warfare agents that pose significant acute and chronic dangers to military forces. There are no current therapeutic treatments for exposure to such toxic agents and there is an urgent need to develop a therapeutic drug which is capable of efficiently sequestering the toxic molecules and facilitating their excretion in vivo. L ...

ABSTRACT: Mycotoxins are lipophilic agents derived from fungus that pose a significant public health problem around the world. The effects of mycotoxins include loss of human and animal life, increased healthcare and veterinary costs, reduced livestock production, and disposal of contaminated foods and feeds. Mycotoxins, such as aflatoxin and T-2 mycotoxins, have been reported to be weaponized as ...

ABSTRACT: Energy harvesting has emerged as a critical need for many current and future Air Force missions to enable their long lifetime requirements. Traditional approaches have focused on harvesting solar and vibration (i.e., via the use of piezoelectric materials) energy. More recently, substantial interest has developed in harvesting energy derived from thermal gradients (e.g., due to solar ...

ABSTRACT: Thermoelectric (TE) devices already found a wide range of commercial, military and aerospace applications. However, at present commercially available TE devices typically offer limited heat to electricity conversion efficiencies, well below the fundamental thermodynamic limit, calling for the development of higher efficiency materials. The team of MicroXact Inc., Virginia Tech and Sunde ...
